Astronomers have been finding exoplanets orbiting distant stars for years now, but rarely have they ever spotted a collection of planets arranged like our own solar system. Recent examinations of the star KOI-351 have revealed more planets than were previously known to exist. The new discoveries bring the total to a record seven planets orbiting KOI-351, and they’re arranged in the same way the planets of our solar system are — small rocky planets closer to the star and gas giants farther out.

The new observations were carried out by a team at the German Aerospace Center (DLR) under the supervision of Juan Cabrera. The team was able to study the light curve from the star using new algorithms to detect the dips in luminosity from planets transiting the star’s corona. They identified four more planets roughly the size of Earth (or a little bigger) close to the star. Two of the newly detected planets are only 19% and 31% larger than Earth. It would not have been possible to spot these planets absent the team’s new algorithms.

While the arrangement and number of planets around KOI-351 are similar to our solar system, there is one notable difference. The planets are all pressed in much closer to the star, with the closest ones whipping around the star once every seven and nine days. The other rocky planets have orbital periods of 60, 92, and 125 days. Although, one of these might be a very small gas giant. The big gas giants orbit KOI-351 in about 211 and 331 days. Thus, the entire solar system discovered by astronomers is compressed into a space the same as the distance between Earth and the sun.

The KOI-351 system is fascinating, but we probably won’t get a chance to see it up close in the foreseeable future — KOI-351 is about 2500 light years away from Earth.
